S. frugiperda insect ovarian cell line Sf 21-derived recombinant human HGF (R&D Systems, Catalog # 294-HG)
Gln32-Ser728
Accession # P14210
Formulation
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
Endotoxin Level
<0.10 EU per 1 μg of the antibody by the LAL method.
Label

Applications

Recommended Concentration
Sample
Western Blot
1 µg/mL
Recombinant Human HGF (Catalog # 294-HG)
Neutralization
Measured by its ability to neutralize HGF-induced IL-11 secretion in the Saos‑2 human osteosarcoma cell line. Hjertner, O. et al. (1999) Blood 94:3883. The Neutralization Dose (ND50) is typically <2 μg/mL in the presence of 3 ng/mL Recombinant Human HGF.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

IL-11 Secretion Induced by HGF and Neutralization by Human HGF Antibody. Recombinant Human HGF (Catalog # 294-HGN) induces IL-11 secretion in the Saos-2 human osteosarcoma cell line. The dose-dependent response (orange line) is measured by the Human IL-11 Duoset (Catalog # DY218). Under these conditions, IL-11 secretion elicited by HGF is neutralized (green line) by increasing concentrations of Goat Anti-Human HGF Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-294-NA). The ND50 is typically 2 μg/mL.

Background: HGF

HGF, also known as scatter factor and hepatopoietin A, is a pleiotropic protein in the plasminogen subfamily of S1 peptidases. It is a multidomain molecule that includes an N-terminal PAN/APPLE-like domain, four Kringle domains, and a serine proteinase-like domain that has no detectable protease activity. Human HGF is secreted as an inactive 728 amino acid (aa) single chain propeptide. It is cleaved after the fourth Kringle domain by a serine protease to form bioactive disulfide‑linked HGF with a 60 kDa alpha  and 30 kDa beta chain. Alternate splicing generates human HGF isoforms that lack the proteinase-like domain and different numbers of the Kringle domains. Human HGF shares 91%‑94% aa sequence identity with bovine, canine, feline, mouse, and rat HGF. HGF binds heparan-sulfate proteoglycans and the widely expressed receptor tyrosine kinase, HGF R/c-MET. HGF-dependent c-MET activation is implicated in the development of many human cancers. HGF regulates epithelial morphogenesis by inducing cell scattering and branching tubulogenesis. HGF induces the upregulation of integrin alpha 2 beta 1 in epithelial cells by a selective increase in alpha 2 gene transcription. This integrin serves as a collagen I receptor, and its blockade disrupts epithelial cell branching tubulogenesis. HGF can also alter epithelium morphology by the induction of nectin-1 alpha  ectodomain shedding, an adhesion protein component of adherens junctions. In the thyroid, HGF induces the proliferation, motility, and loss of differentiation markers of thyrocytes and inhibits TSH-stimulated iodine uptake. HGF promotes the motility of cardiac stem cells in damaged myocardium.
